JESSE JAMES WARNER, or PABKERSBURG, wEsT irrn'erivm ELECTROMEDICALAPPARATUS.

Application filed June 18, 1913.

To all whom it ma concern 7 Be it known that I, JEssE J. WARNER, acitizen of the United States, residing at Parkersburg', in the county ofWood and State of West Virginia, have invented certain new and usefulImprovements in Electromedical Apparatus; and I do declare the followingto be a full, clear,-and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make,and use the same, reference being had to the accompanying drawings, andto the letters and figures of refer. ence marked thereon, which form apart of this pecification. I

This invention relates to improvements in what may be termedelectro-medical apparatus designed as indicated, more especially formedical or surgical purposes, the same relating more particularly tothat type of electrical machines wherein a direct continuous'current,such as is generated by a shuntwound dynamo, driven from any suitablesource of power, asa water-motor, an elec-- tric motor or otherwise, maybe changed or converted into an alternating or sinuous cur-' In theaccompanying drawing is illustrated the preferred embodiment of myinvention wherein it will be understood that various changes andmodifications may be made as relate to the detailed construction andarrangement of the parts without departingfrom the spirit of-theinvention as embraced in the claim, and in which drawm Tigure 1' is avertical longitudinal section with the circuit wires discloseddiagrammatically of the machine. Fig. 2 is an enlarged detailed planview showing more particularly the rheostat and the resistance coilSpecification of Letters Patent.

suitably wired to the generator terminals. Fig. 8 and Fig. 3 representviews in vertical section and in end elevation of the'commutator andadjunctive parts, together with the brushes, the brush wires and brushholder, certain'of these parts being shown fragmentarily, as is also thecommutator carrying shaft. Fig. 4 is a plan view of the machine with theclosure of thecontaining receptacle or case displaced, showing more'oart'icularly the dial, its index and the index actuating or adjustingfinger piece equipped shaft or controller adjunctive of the rheostat;the apertures or passages for the insertion of the wires and themanually engaged plugs attached to said wires, the lubricant feedingmeans for the bearings of the generator and motor being disclosed inoutline. Fig. 5 is a' fragmentary partly sec tional' view and partlydiagraimnaticalview of the machine, disclosing more particularly thecommutator, therhe'ostat with its resistance coil and the electricalgenerator wiring with its wire terminals.

In carrying out my invention, I employ a motor 1, preferably ofwater-wheel type, or it may be of electrical character or otherwise, acommutator 2, an electrical generator 3, a rheostat 4 and a resistancecoil 5, all being suitably housed within a casing 1 the water-wheel ofthe first named being attached to and driving a shaft 6 carrying orrotating the commutator and actuating the generator, said shaft beingjournal-ed in suitable bearings 7 in the form of castings secured to thebottom of and within the casing 1; a water-inlet is provided through thecasing 1" in the form of a nozzle 1" to which may be connected awater-hose.

i The castings, forming the bearings 7, are adapted to provide forfeeding lubricant to the shaft 6 by the aid of feeding devices 6suitably applied to said castings or bearings and actuated by means ofwires or flexible connections 9 secured-to said feeding devices andextending through apertures in the casing I for convenient manipulationby the attendant. y l v i The commutator 2, circular in general outline,as usual, includes in its makeup or composition copper-members 2, saidcopper members having opposed spaced-apart alternating or staggeredrectangular extensions or projections 2 for the reception therebetweenof a continuous member or segment 2 of non-conducting material, the samethus assuming a tortuous or sinuous outline, the projections orextensions 2 thus adapted to be intercepted by a medium lineperimetrieally encompassing the commutator.

The rheostat l has a circular series or arrangement of contact points 4,and centrally, and independently movable thereof is a shaft orcontroller 10 carrying a contact finger 11, the direction of movementthereof being indicated by the arrow, and which contact finger isadapted to be moved over the face of said rheostat and engage any of thecontact points 1 thereof for controlling the amount of voltage to beused in treating the patient medically or in using the device forsurgical purposes, as will be presently made more clearly apparent. Astop 11 suitably secured to the face of the rheostat prevents theinitial movement of the contact finger 11 in the wrong direction andlimits the extent of the reverse movement thereof when it is required toreturn the contact finger to initial position. This shaft or controllerhas applied or attached to its upper end a knurled finger piece or disk10 adapted to provide for the convenient manual actuation of said shaftor controller, said shaft or controller also be ing equipped with anindex or pointer l0 playing over a dial 12 suitably arranged upon thecasing 1 and graduated for the purposes of this machine for indicatingthe raising and lowering of the voltage according to the requirements ofthe case under treatment.

Plugs 13 are provided for insertion into the terminals 1 1 seated innon-conducting material in the closure of the casing, to which plugs aredesigned to be applied suitable hand-holds for the person to grasp whilebeing treated, said terminals being tubular to receive said plugs andbeing suitably seated in the upper part of the casing.

The rheostat 4 is suitably wired or connected by wires 15 to theresistance coil 5, a wire connection being effected between each of theplurality of contact members 4t and each of the individual helices ofthe resistance coil as seen in Figs. 2 and 5, the shaft or controller 10and the rheostat being connected to the generator terminals 16 and 17 bywires 18 and 19, respectively.

The shunt-wound generator or dynamo 3 is connected by wires 3 3, leadingfrom the brushes of the latter to the terminals 16 and 27 the windingsof the armature 3 being connected as at 3 to the terminal 17.

Brushes 20, 21, 22 and 23 are applied to or engage alternate orstaggered commutator segments or members 2 and 2 throughout theperimetric surface of the commutator as it is rotated through the shaft6 from the motor 1, these brushes including their holders 20 andparallel supports or brackets 21 receiving the brush-holders, saidsupports, themselves, being supported from base-irons or members 2 1 soas to allow of the presentation of the brushes to the perimetric surfaceof the commutator as seen particularly in Fig. 3. The brushes 20 and 21are connected by wires 25 and 2G to the generator terminals 16 and 27 asseen in Figs. 1 and 5, which thus provide for the flow of the directcurrent through said brushes to the commutator segments or members 2,2", providing for the maintenance of these segments 01' members alwayscharged with the same kind of current (positive or negative). As thecommutator continues to rotate the brushes 22 and 23 connected by wires28 and 29 to the handheld plug-receiving terminals 14 alternately engagethe segments or'members 2, 2 of said commutator, thus providing foralternately changing the current in the wires 28 and 29 from positive tonegative electricity at each engagement of these segments and brushes inthe rotation of the commutator, as in the application or using of thedevice.

From the foregoing it is thought that the operation of the invention hasbeen made clearly apparent, it only being necessary to add, possibly,that the operator or person receiving the treatment grasps the handholds(not shown) or other conductors attached to the plugs 13 and applies thelast referred to parts to the tubular terminals 1 1 in electricalcircuit with the brushes 20 and 21. The requisite electrical currentwill be generated and the operator or patient accordingly receive anelectrical shock from the current which will be directed through thearms and shoulders, it being understood that the controller 10 issuitably actuated for controlling the voltage as called for under theattending conditions.

I have found that in the use or application of my invention positive andalmost instant relief from headache, female troubles, as well as manyother ailments, is realized, the invention therefore being highlyeffective as a curative agent both for medical and surgical purposes asabove indicated.

I claim:

An electro-medical apparatus including a motor, its shaft, a commutatormounted upon said shaft, a shunt-wound electrical generator actuated bysaid shaft, said commutator comprising annular complemental membershaving intermediate thereof a sinuous insulating member, providing forchang ing the direct current from said electrical generator into analternating current, a rheostat having a circular arrangement ofperipheral contacts and indicia registering With said contactsindicating voltage, brushes Wired to said complemental members of saidcommutator and to the terminals of said electric generator, a controllershaft equipped With a finger arranged to engage said contacts of therheostat, said controller shaft and rheostat being Wired to saidelectrical generator, manually actuated members Wired to certain of thebrushes and equipped With hand-holds.

In testimony whereof, I afiix my signature, in presence of twoWitnesses.
